Septic Systems

Building Outside City Limits Means You Need a Septic Permit

Most of Tyler County has no sewer service, so new homes and additions require a permitted on-site sewage system before construction begins.

Most land in Tyler County is rural and not connected to a public sewer. If you build a home or add a bedroom, you will need a septic system — called an OSSF (on-site sewage facility) in Texas. You must get a permit before you install it.

The county is usually the permitting authority for septic systems, not TCEQ directly. You will need a licensed site evaluator to test the soil and layout before a permit is issued. Sandy or clay-heavy Piney Woods soils affect what type of system is allowed. Do not assume one type works everywhere. Start with TCEQ's OSSF homeowner page for the process, then contact Tyler County to find the local permitting contact.
